Abstract: Absorbent (I) for removing acid gases (II) from fluids comprises (a) tertiary alkanolamine(s) and (b) an amine selected from hydroxyethylpiperazine, bis(hydroxyethylpiperazine or a mixture of these. An independent claim is also included for a process for absorption of (II) from fluid streams by contacting the fluid stream with absorbent (I) to give a fluid stream depleted in (II) and (I) charged with (II).

Abstract: In a process to reduce the acid content in a fluid flow, the gas is brought into contact with an aqueous absorbent containing methyl-diethanolamine and piperazine. The total amine content is in the range 20-70% by weight of the absorption agent. The ratio by weight of methyl-diethanolamine to piperazine is in the range 9-15. The process uses an absorbent in which the total amine content is in the range of 45-55% by weight. The ratio of methyl-diethanolamine to piperazine is in the range of 13-15. The absorption process is conducted in two sequential stages. The process further incorporates a regeneration phase consisting of one or more expansion phases in which acid is expelled from the absorbent and the absorbent re-used. An Independent claim is included for an aqueous absorption agent containing methyl-diethanolamine and piperazine.

Abstract: A method is provided for removing acid gases and ammonia from a fluid stream in which a fluid stream comprising acid gases and ammonia is brought into contact with an aqueous absorption medium. The fluid stream is depleted of acid gases and ammonia and the absorption medium stream, which is charged with acid gases and ammonia, is regenerated in a desorption step. The acid gases and the ammonia are stripped out of the absorption medium and the condensable fractions thereof are condensed. A condensate and also a purified absorption medium stream are obtained. The condensate is ejected in part or completely from the desorption step, or feed in part or completely to a distillation column in which ammonia is separated off overhead as an aqueous solution or in the pure state. A aqueous bottom stream is obtained which is recycled to the absorption step or the desorption step.

Abstract: The invention relates to the use of an alkylene diamine of formula R1HN-X-NHR2, wherein X represents an alkylene radical comprising 2 to 9 C atoms, R1 represents a hydrocarbon radical comprising 1 to 6 C atoms, and R2 represents a hydrocarbon radical comprising 1 to 6 C atoms or a hydrogen atom (H), for removing acid gas from a stream of fluid containing acid gas. The invention also relates to a method for neutralising one such stream of fluid, and a washing or absorption liquid for use in one such method. According to the invention, the stream of fluid is brought into intimate contact with a washing liquid in at least one absorption step, said washing liquid containing an aqueous amine solution which has at least one tertiary aliphatic alkanolamine comprising 2 to 12 C atoms, and an activator of said formula R1HN-X-NHR2. Finally, the stream of fluid which has been extensively cleared of acid gas is separated from the washing liquid which is loaded with acid gas.

Abstract: The invention relates to a method for removing mercaptans from fluid fluxes containing mercaptans, in particular from hydrocarbon gases, such as natural gas, synthesis gas from heavy oil or heavy residues or refinery gas, or also from liquid hydrocarbons, for example, LPG (liquefied petroleum gas). According to the invention, a fluid flux of this type is brought into contact with a washing solvent in an absorption or extraction zone. Said solvent contains at least one aliphatic alkanolamine which has 2 - 12 C-atoms. Enough washing solvent is supplied to the absorption or extraction zone to more or less completely eliminate at least CO2 and H2S from the fluid flux. The substantially purified fluid flux is subsequently separated from the charged washing solvent and both the fluid flux and the washing solvent are evacuated from the absorption zone. The major part of the mercaptans are removed from the gas flux by the more or less complete removal of CO2 and H2S, without a notable portion of the hydrocarbon gases dissolving in the washing solvent.

Abstract: The absorbent consists of a mixture containing: (a) 1-50 wt.% unsubstituted mono-or bi-cyclic nitrogen heterocycles with 5-14 ring atoms or substituted with OH, 1-3 C alkyl and/or 1-3 C hydroxyalkyl, and 1 or 2 heterocyclically bound nitrogen atoms; (b) 1-60 wt.% mono- and/or multivalent alcohol; (c) 0-50 wt.% aliphatic aminoalcohol; (d) 0-98 wt.% water; and (e) 0-35 wt.% potassium carbonate. Process for removing acidic components, e.g. carbon dioxide, hydrogen sulfide, COS, carbon disulfide and mercaptans from gases comprises contacting the crude gas with an adsorbent obtaining a pure gas deficient in acidic gas components and an absorbent charged with acidic gas components. The absorbent consists of a mixture containing: (a) 1-50 wt.% unsubstituted mono-or bi-cyclic nitrogen heterocycles with 5-14 ring atoms or substituted with OH, 1-3 C alkyl and/or 1-3 C hydroxyalkyl, and 1 or 2 heterocyclically bound nitrogen atoms; (b) 1-60 wt.% mono- and/or multivalent alcohol; (c) 0-50 wt.% aliphatic aminoalcohol; (d) 0-98 wt.% water; and (e) 0-35 wt.% potassium carbonate.

Abstract: Method for simulation of mass transport controlled separation processes in which a core-film layer is used to describe a mass exchange taking place at a phase border (P). According to the approach, an iterative solution of an implicit differential equation system is undertaken for discretization of an observed transfer area (10) of the core-film layer, from which the differential equation system, especially based on the Stefan-Maxwell equation, is generated. An independent claim is made for a device for simulation of mass transport controlled separation processes in which a core-film layer is used to describe a mass exchange taking place at a phase border.

Abstract: Disclosed is a method for deacidifying a fluid stream containing acidic gases as contaminants, according to which the fluid stream is brought into intimate contact with a washing liquid in at least one absorption step. Said washing liquid represents an aqueous solution containing a) tertiary aliphatic alkanolamines (alkanolamine A), at least 30 percent by weight of said tertiary aliphatic alkanolamines being 3-dimethylamino-1-propanol, and b) secondary aliphatic amines (activator B), at least 20 percent by weight of said secondary aliphatic amines being piperazin. The fluid stream which has been essentially purified of the acidic gases is then separated from the washing liquid that is loaded with acidic gases.
